I hope so. Companion changes are much more fun when the new companion really feels different from the old one. I think part of the reason I was never a huge Martha fan was that she didn't feel different enough from Rose to me (and part of the reason I liked Donna was because she did feel different). Amy's great, but I hope the new companion is very different.

From what they've said she sounds like she will have an interesting story behind her and will be a little challenging (what they said about her being cast because she could talk faster than Smith is an interesting note).

Have you seen the classic series? Sarah Jane is wonderful and really the breakthrough companion, and Romana is a Time Lady and acts almost like the Doctor's sister. They both are among my favorites.

That sounds good. I like the idea of a companion with a backstory, especially since we haven't really had that so far (at least in the new series). It seems like something Steven Moffat would do, also.

I can think of several reasons they might want this, and not a single one of them wouldn't be hilarious. I am all for a companion who can out-talk the Doctor, that sounds incredibly entertaining.

I haven't, I just caught up with the 2005 series. I'm planning to go check out the classics at some point, but it's a bit intimidating because there's just so many of them. I'm normally the kind of person who likes to start a show at the beginning and watch it all the way through, never skipping or cherry picking, but that seems like it would be difficult (partially impossible) with the classic series and I haven't decided how to approach it yet.

It does look very intimidating, and I really have only seen bits and pieces here and there. It is very stand-alone (albeit being made up of serials made up of several episodes, and the season that is the Key to Time arc) so it is okay to skip around. It is also nearly impossible to watch all the way through due to a lot of the earlier ones being missing. I'd start with the first two serials (An Unearthly Child, The Daleks) to see how it all begins. Then if you want you could skip to what little there is of the Second Doctor (most of them were wiped) like Tomb of the Cyberman. The Third Doctor is a little comparable with the Eleventh, as it starts a new era (in color for the first time, on Earth with UNIT, also where the Master first appeared). Spearhead from Space is his first (The Time Warrior is the first for Sarah Jane, if you are interested in her). Then there is a ton of Fourth Doctor stuff which is among the most famous--check out City of Death (written by Douglas Adams), The Ark in Space, Pyramids of Mars, and The Horror of Fang Rock next. Granted, most of these I've only seen a little bit of and I'm basing this mostly on reputation.

So 11 wanting to wear a fez, the others making fun of it, and River shooting it is a sign of their great chemistry? Really? Not to imply that they don't have good chemistry, but this is a shitty example.

River and Amy constantly mocking 11, including the way he dresses (the bowtie, most notably), is part of their extremely entertaining dynamic. The fez is an example of that. It might not be the best example, but I assume that's why it got brought up here. Because awe300 thought about the fez scene, and that reminded him/her of how entertaining the chemistry between those characters is.

I can already see one of the scenes. the doctor is fumbling about with his sonic screwdriver trying to do something amazing but taking much too much time doing it. meanwhile indy is holding off the enemy in an epic fistfight while giving the doctor exasperated looks.

Still, though, the obsession that fandom has with that one piece of clothing that appeared in one, maybe two episodes at the most, is the reason why I switched /r/doctorwho with /r/gallifrey on my dashboard.

And continues to be a joke, probably into perpetuity. 10 donned aviator glasses and a motorcycle helmet in "The Idiot's Lantern", and I'm sure there are hundreds of other examples of the Doctor wearing one-off accessories through hundreds of other episodes and stories and serials.

My friend and I recreated that moment (almost...)
I went round her house just after she'd finished doing her hair (bear with me its relevant)
She said,
"What the Hell have you got on your head?"
Me: "I wear a straw hat now, Straw hats are cool"
and then she shot it off with her hairdryer!
(Well she would off, if it had still been plugged in, which would have been epic!)
